摘要
用氟锆酸钾、有机二酸处理羊毛毛线 ,用热分析、剩碳率及氧指数等分析方法对其阻燃性进行了研究 ,并用Kissinger方程计算热降解反应活化能 ,实验证明 :经过阻燃处理的羊毛毛线比未经阻燃处理的羊毛毛线的剩碳率、氧指数均有所提高 ,热降解反应活化能和热分解温度降低。
Studied the wool treated with potassium hexafluorozirconate and carboxylic diacid by thermal analysis,infrared spectroscopy and by measurment of the limiting oxygen index(LOI). The kinetics parameters were obtained by using the equations of kidssinger.The activation energies were calculated for the docomposition of untreated and treated wool.Experimental data showed that for the wool treated with flame-retardant reagents the data of char yield and LOI increased,and the activation energy and temperature of decomposition decreased
